Abstract (en)

[origin: EP0766492A2] The method involves using a time-multiplexed transmission channel commonly by a number of transmitters, for the transmission of binary encoded digital data. The bits of one of the digital values are represented by a potential, which overrides the potential of the other digital value, when both values are output on the channel. To avoid usage of the channel by two transmitters simultaneously, a monitoring channel is provided, where the transmitters also output their data, at the same time as on the transmission channel. The monitoring channel enables the transmitters to detect any data collision on the channel, by outputting a value and monitoring the condition of the potential on the channel. Each transmitter outputs an individual address code prior to any transmission, an reads the monitoring channel to detect any collision, after which it interrupts its transmission. Prior to the channel testing procedure, each transmitter sends before any data transmission a test impulse onto the transmission channel, in any empty time slice, an detects if the time slice is empty for transmission.
